Frequently Asked Questions
-
What is the typical lead time for a segmented girth gear?
Lead time depends on size and complexity, but generally ranges from 8 to 16 weeks. We can expedite urgent orders with prior arrangement. -
Can you machine the gear to match an existing pinion?
Yes, we can reverse-engineer your existing pinion and gear dimensions to ensure perfect meshing. Please provide drawings or worn samples. -
How are the segments joined together?
Segments are precisely machined with mating surfaces and bolted using high-strength fasteners. Dowel pins ensure alignment. Detailed assembly instructions are provided. -
What is the maximum weight per segment?
We can handle segments up to 15 tons individually. For larger gears, we design lightweight segments to facilitate handling. -
Do you offer field installation support?
We provide technical guidance and on-site training upon request. Our engineering team can also supervise initial installation. -
Is the 42CrMo4 material suitable for high-temperature environments?
42CrMo4 retains strength up to about 400°C. For higher temperatures, we can recommend alternative materials like 4340 or heat-resistant alloys. -
What inspections are performed before shipment?
Every gear undergoes dimensional inspection, hardness testing, magnetic particle inspection for surface cracks, and ultrasonic testing for internal defects. A certificate of conformance is issued. -
Can you provide a design for a specific module other than 20?
Absolutely. We can customize module, pressure angle, number of teeth, and face width to your requirements. Contact our engineering team with your specifications.
